TL;DR: In this paper, the authors analyzed three blowout attributed to high pH SCC in different oil and natural gas transmission pipelines, which occurred by the sudden propagation of longitudinal cracks at the outer surface of the pipes.

TL;DR: Stress corrosion cracking (SCC) studies in stainless steels and nickel alloys reveal that all grades and conditions are susceptible to SCC in high-temperature water, whether deaerated or aerated, high H2 or low, theoretical purity water or buffered/contaminated, lower temperature or higher.
Abstract: Stress corrosion cracking (SCC) studies in stainless steels and nickel alloys reveal that all grades and conditions are susceptible to SCC in high-temperature water, whether deaerated or aerated, high H2 or low, theoretical purity water or buffered/contaminated, lower temperature or higher. However, the kinetics of SCC growth vary enormously with stress intensity, yield strength, sensitization, water chemistry, irradiation, temperature, etc. The role of yield strength is especially important because it changes with surface cold work, bulk cold work, weld shrinkage strain, and irradiation hardening; the role of metallurgical strengthening mechanisms, e.g., nitrogen additions or precipitation hardening, may have a similar effect. SCC growth rate measurements were performed in high-temperature water on unsensitized stainless steels (and Alloy 600 [UNS N06600]) of various grades and compositions. Little effect of grade/heat of stainless steel, martensite content, or H2 fugacity/permeation rate was ob...

TL;DR: In this paper, failure mechanisms were determined based on available documents and metallographic studies conducted on a high-pressure gas pipeline steel in northern regions of Iran, after almost 40 years since its installation.

TL;DR: In this paper, a series of experiments determined the threshold stress of various bolt metallurgies (900 MPa for 1355AXRC, and 800 MPA for MAC and MA840B steels) and showed that SCC begins in rock bolts when they are sheared by moving rock strata.

TL;DR: In this article, the effects of prior cold work and sensitization treatment on the stress corrosion cracking (SCC) behavior of Type 304 stainless steels have been studied in chloride solutions using electrochemical tests and magnesium chloride tests with U-bend specimen.
